IMPROVEMENT IN AXLE-BOX.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM H. POLLARD, of Seneca Falls, in the county of Seneca, and State of New York, have invented a certain new and useful Improvement in Axle-Skcin Boxes; and I do hereby declare that the following is a full and exactdescription thcreot', reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a sectional elevation of my improved axle-shein and box.

Figure 2, an elevation of the box removed from place.

Like letters of reference indicate corresponding parts in both figures.

My inv nti n consists in providing the box with circumferential corrugations for holding firmly in the hub, as hereinafter set forth.

As represented in the drawings A is the ordinary aXle-skcin, B the box, and C the nut that holds them together. The box is provided with circumferential corrugations a 11, preferably at opposite ends. It is also provided with corrugated feathers or ribs,b {7, extending longitudinally, as clearly shown. Thus arranged, when the hex is wedged into the hub, the wood sets down over the corrugations and holds the box firmly in place. The corrugations on the feathers or ribs, which prevent the box from turning, also form teeth that hold firm in the Wood and give additional security to the contact. The box thus corrugated is easily formed of a t iron, and very cheaply made. In this respect it is far superior to boxes having a screw for forcing into and holding in the wood. Where a screw is used, not only is it (lifiicult to mal e, but as it must enter longitudinally or diagonally, the box is constantly working out ondwisc, and is very insccurc. In my device, the corrugations being situated crosswise or at right angles to the axis, there is no difiiculty from this source.

I do not claim a box having a screw upon its periphery for holding in the hub, as I. am aware that the same is not now. What I claim as my invention, and desire to'secure by Letters Patent, is

The box A, provided with the corrugations a a, operating in connection with the hub, as herein set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

WM. H. POLL'ARD.
